Controlling the Polymorph of Ln^III(NO₃)_3-x(OH)_x[15-MC_{Cu^II(N)S-pheHA}-5] Complexes through Solvent Type and Ln^III Ion Choice

Abstract

Two general polymorphs of Ln III (NO 3 ) 3-x (OH) x [15-MC Cu II (N)S-pheHA -5] (where

Constructions of helical coordination compounds

“…For the design and constructions of singlestranded helical structures, the most successful approach is to use enantiopure or racemic ligands as building blocks. [13][14][15][16][17][18][19][20][21][22][23][24][25][26] We found that the racemic fourcoordinated nickel(II) 1a). In both meso-1$4.5H 2 O and meso-1$3H 2 O, there are hexameric water clusters of (H 2 O) 6 between two adjacent chains, and the (H 2 O) 6 rings act like a 'mirror plane', the right/left-handed chirality of the original formed chain is transferred opposite to adjacent chains through interchain hydrogen-bonding interactions of hexameric water clusters (Fig.…”

Thermodynamics of binding of carboxylates to amphiphilic Eu3+/Cu2+ metallacrown

“…16 This OHion occupies one of the three coordination positions available on the encapsulated Eu 3+ , ruling out the coordination of carboxylates on this side and leaving only two positions in the hydrophobic side for carboxylate binding. 6 Although the co-crystallization of 1 with 4 promotes the reprotonation of the OH -, this water molecule is not displaced and no 4 anions are bound to Eu 3+ on the hydrophilic face. The phenyl residues of the 1 molecule are oriented toward the coordinated 4 ion to form the hydrophobic pocket.…”

Synthesis, Structure and Properties of a One-Dimensional Cd(II) Complex Based on a Chiral Ligand

“…Solids composed of chiral structures have exhibited many potential applications. These materials can be used as new optical materials for chiral catalysts, new materials for separations, chiral magnetic materials, and so on [5]. However, the rational and reproducible synthetic approach to achieve these materials is still infant [6][7][8].…”
